PAINTING A SPECIFICATION forming part of Letters Patent No. 703,385, dated July 1, 1902.

Serial No. 71,433. (No modeL) To a/ZZ whom it nfl/ty concern:

Beit known that LHENRYDELANO OARRYL, a citizen of the United States, and a resident of the borough of Manhattan, city of New York, and State of New York, have invented certain new and useful Improvements in Apparatus for Painting or Cleansing Surfaces, of which the following is a specification.

My invention relates to an apparatus for painting or cleaning all classes of surfaces, and the same is primarily intended toprovide a system by means of Whichpaint or any other' coloring or any cleaning liquid can beapplied automatically to a brush or other paintingtool in such a Way as to enable a large surface to be treated with the greatest possible economy of cost and time.

At the present time there is no practicable apparatus in actual use by means of which high buildings, bridges, and other similar structures presenting greatl areas of surfaces can be successfully and properly painted or cleaned except by means of implements manually operated 5 and the object of the present invention is to provide apracticable, simple, compact, easily-operated, and reliable mechanism for painting or cleansing large surfaces. v

A great many forms of apparatus have heretofore been devised for spraying or ejecting liquids from a movable nozzle by means of compressed air, and'some of them have undertaken to paint by means of a stream of paint forced by compressed air into a brush or else through a spraying-nozzle.

In the case of an ordinary light easily-flowing liquidsuch,'for example, as is used in the ordinary form of portable garden-sprayers-it is possible to successfully and effectually eject the liquid by means ol' any form of pumprwhich not alone may supply a liquid-A tank from which the liquid is ejected, but also which may in-itself create the air-pressure. Where, however, a'heavy or sluggish material is used, such as paint, which has to be ejected from a dense and more or less homogeneous'body, like a brush which constantly divides the stream at a great many points and reduces the pressure, the ordinary form of light spraying device which is found in many forms of garden-sprayers or syringes will be useless for the reason that a pressure cannot be maintained except for a very short time, and the moment that the pressure falls the tool ceases to be effectual and operation unsuccessful. Again, in all of these forms of apparatus when the apparatus is to be reilledrthe chamber has to be opened and the pressure after filling restored, or else the Work has to be constantly stopped to pump in air andmaterial together.

l have discovered that where the tank containing the liquid is provided with an independent air-compressing device which is of such construction that by means of it the pressure in the tank may be kept substantially constant without reference to the amount of liquid in the same, and if a pump be provided whereby the tank may be supplied with the liquid to be used in painting from time to time, as may be necessary, it will be possible to produce an apparatus which will enable the heaviest class of liquid to be. used in a brush without appreciable loss of pressure in the chamber in which the liquid is stored.

The system which is embodied in the present invention may be briefly characterized as consisting of, lirst, a portable chamber arranged to contain a suitable painting or cleaning material upon which air-pressure can beconstantly exerted, so as to produce an automatic discharge of the material at the will of the operator; second,a'iiexible tu be through which the paint is supplied to the brush or other tool; third, a suitable 'brush or cleaning-tool which will Vary from time to time in form or position, according to the particular surface to which the paint or cleaning liquid is to be applied; fourth, an independent pump or other suitable pressure-creating device whereby the pressure is applied to the liquid in the reservoir; fifth, a device, preferably a pump, for supplying the paint or other fluid to the reservoir either automatically, by gravity, or by hand, and, preferably, sixth, an independent auxiliary air-chamber used to accumulate any liquid that may overflow from "the main chamber and prevent same from entering pressure-gage, and, seventh, an arrangement of valves whereby the apparatus and paint-conducting agencies may IOO from time to time be cleaned out without dis turbing the material or pressure in the pressure-chamber.

The invention will be best understood by reference to the accompanying three sheets of drawings, forming a part of this speciiication, in which- Figure l is a diagrammatic View of the apparatus. Fig. 2 is a vertical elevation of the apparatus, showing its component parts and its method of operation; and Fig. 3 is a plan view of the apparatus.

Similariigures refer to similar parts throughout the several views.

In the drawings, 7 represents a pail or other receptacle forming a reservoir in which paint or any other coloring or cleansing medium is contained.

2 is a chamber into which the painting or cleansing material is introduced through the pipe 3 by means of a force-pump 4.

5 isa stand upon which the chamber 2 rests, provided with rollers 34 and 34.

6 is a flexible hose of suitable length connecting the chamber 2 with the receptacle 7 in the manner hereinafter described.

Chamber 2 is preferably made of metal and cylindrical, as shown, and is firmly attached to the stand 5 in any convenient manner. The force-pu mp 4 is attached to the stand 5 by the screws and consists of a piston-rod 10, sliding in the cylinder 4, provided with a piston-head 1l, Fig. 1, and is operated by the lever-arms 13, connected by the handle 12. The pipe 3 is connected with the force-pump 4 by ihe pipe 8, which entersat the bottom of the cylinder below I[he piston 1l, as shown in Fig. 1, and on either side of the point where the pipe 8 connects with the pipe 3 two check-valves l5 and 17 of the ordinary construction are provided. The horizontal pipe 3 is connected with the chamber 2 by means of the pipe 9. This pipe contains an ordinary cutoff valve 16, actuated by the handle 30. One end of the pipe 3 is connected with a hose 6, the other extremity of which hose passes into the receptacle 7. A cut-off valve 14, having a handle 21, is placed in the pipe 3 beyond the point where the pipe 9 connects with it, whereby the flow from the end of the pipe may be controlled. An air-pump'18, with a piston 19, which is generally of similar construction to the force-pump 4, is provided upon the stand 5, placed, preferably, as shown in Fig. 3, at the side of the force-pump 4 and attached to the stand 5 by means of asimilar series of screws 51. This is actuated by means of two levers 23,-connected by a handle 22. The compressor is shown in the diagrammatic View, Fig. 1, and by means of it compressed air is caused to enter the upper part of the chamber 2 through the pipes 2O and 38. Thepipe 20 contains stop-cock 37, placed at any convenient position for the purposes hereinafter specified. The air-pump is of any convenient type and, as is shown on the right, is operated by ordinary hand-levers and may be placed at any convenient position upon the stand 5 with reference to the chamber 2. The chamber 2 is closed by a cap 21, screwed into position in any convenient manner. In order to prevent the material entering from the force-pump 4 into the chamber 2 from flowing back into the receptacle 7, the two check-valves 17 and 15 are provided, as shown. When the materialenters through the check-Valve 17 into the interior of the force-pump, this valve is opened by the movement of the piston 11, this material is forced through the check-valve 15 and thence through the pipe 9 into the chamber 2, and as soon as it passes the check-valve 15 the latter shuts and prevents its return. Any convenient manner of attaching the flexible hose 6 to the pipe 3 may be employed.

1 is a brush of any convenient form, which is attached, by means of an adjustable hingejoint 39, to a handle 24.

25 is avalve by means of which the supply of liquid entering the handle can be regulated. The lower end of the handle 24 is coupled by the union 26 of a iiexible hose 27 of any convenient length. The other end of the hose :is attached to a pipe 41, emerging from the chamber 2. The ow of liquid from the chamber into the hose 27 is controlled by a valve 28, actuated by a handle 29.

A pressure-gage is provided,which serves to indicate the pressure in the chamber2, and in order to prevent any paint or cleansing material from entering the pressure-gage and clogging it and preventing it from working satisfactorily it is fou nd convenient to insert a supplemental chamber 61 between the aircompressor 18 and the chamber 2. sists of an ordinary air-chamber connected at the bottom with the top of the chamber 2 by means of the pipe 38 and provided with an escape-valve 39 at the bottom. The air from the air-compressor 18 enters this by means of the pipe 20, controlled by the check-valve 62 and the cut-off 37. The bottom of chamber 2 is provided with an outlet-valve 64,by which its contents may be drawn 0E from time to time, if desired.

The method of operation is as follows: Paint or other similar coloring or cleansing material is placed in the receptacle 7, and the loose end of the hose 6 is inserted therein. The hand-pump 4 is then put into operation by moving the handle up and down. The valve 16 is opened and the valve 14 is closed, and as a consequence the paint or other material will be forced from the receptacle 7 into the interior of the chamber 2 and gradually rise therein. As soon as a sufficient yamount of material has accumulated in the chamber 2 the valve 16 is then closed by turning the handle 30, and the air-compressor 18 is actuated by the handle 22, and as a consequence the air will be compressed in the upper part of the chamber 2, and a pressure of any convenient number of atmospheres will be produced in the interior thereof. This pressure This con- 'ICO ICS

IIO

can be determined by the movement of the i with the receptacle for introducing-the `mate-` ngcr upon the dial of the pressure-gage 60. Vhen it is desired to apply the paint or other material, the valve 16 is closed and the valve 28 is opened by turning the ha'ndle 29, and the effect of the pressure in the chamber 2 will be such as to cause the material to iiow through the pipe 41 into the ilexible hose 27 and automaticaily and continuously enter through an appropriate tube in the handle 24 of the brush when the valve 25 is opened. This valve may be of any convenient construction,and therefore the position is merely indicated by numeral in Fig. 8. The hose is suiiciently long to enable the operator to take the handle ot the brush 24 in his hands and move it to any convenient place and paint any convenient surface without reference to the position of the apparatus upon the stand 5. As soon as the pressure in the chamber diminishes to such an extent that the paint no longer flows freely through the brush all that the operator has to do is to close the valve 2S and move the handle 22 of the airpump 18 a few times, and thus restore the pressure of the chamber 2 to what it originally was. The operator thereupon opens the valve 28, and in this way the operation will be continued until pressure drops again, the control ot` the fiow through the handle being eiected, as before, by means of the valve 25. Vhen it is desired to wash out the brush or apparatus, `the tube o may be withdrawn from the receptacle 7 and placed in a similar receptacle containing water, benzin, naphtha, or any other convenient cleansing substance, which substance may then in similar manner be pumped into the chamber 2 by means of the hand-pump 4 and then forced through the brush, in the same manner as the paint, by means ot' the compressed air resultant i from the operation of the air-pu mp 18. Vhen it is desired to wash out the brush directly without causing the washing fluid to traverse the chamber 2, the hose 27 may be attached to the coupling 32 at the end of the pipe 3. The valve 16 will then be closed and the valve 14 opened, whereupon the cleansing material will pass directlyfrom the receptacle into the pump 4 and be forced by the operation of the force-pump through the brush, thus thoroughly and expeditiously cleansing the brush, hose 6, and all its various connections, and yet at the same time the liquid in thereceptacle 2 and the pressure thereon will remain undisturbed. By opening the valve 64 the contents ofthe chamber 2 maybe from time to time, as may be desired, readily` removed.

I claim as my invention- 1. In a portable apparatus for painting or cleansing surfaces,the combination of a chamber and a suitable base or stand, a supplemental chamber connected therewith, a receptacle for containing the painting or cleansing material, a pump connected with the principal chamber and arranged to be connected rial into the chamber in convenient quantities, an independent air-compressor connected with said supplemental chamber `by a suitable pipe for causing the air in the chamber to be compressed and the material to flow automatically therefrom, a portable hand-tool arranged to paint or cleanse, a flexible` conducting-hose connectingthe chamber with` the tool, whereby the painting or cleansing material can be introduced into the tooland a valve in the handle of the Itool for controlling the supply `of the material to it through the hose.
